Justin Bieber Unconcious After 'Slamming' Into Glass Wall, Falling Down Stairs (VIDEO)

Justin Bieber was unconscious for four to five minutes after slamming into a glass partition and falling down a flight of stairs at his concert in Paris on May 31.

Justin Bieber unconscious state didn't last long, according to his manager, Scooter Braun, but the Canadian pop star's entourage was no less concerned. His NBC special "Justin Bieber: All Around the World" showed the 18-year-old heartthrob tried his best to remain stable even though he felt "weak."

Bieber was performing one of his songs during the concert, then exited the stage quickly, banging his head into a glass wall he didn't see clearly. Despite the injury, he decided to continue with the show, and went on stage to perform again.

"It really hurt and I felt a little light-headed, but my adrenaline, I feel, pushed me through it and I performed the last song," the teen told TMZ later in the day.

However, the adrenaline wouldn't last long. Bieber would find his legs giving way under him soon after the incident.

"After that I wenty backstage and immediately felt a little weak," Bieber explained.

In the video, Bieber is seen accompanied by his team after leaving the stage, and he begins heading down the stairs. After a few steps, though, he collapses. Panicked yells for water are heard as the pop star's entourage rushes to his side. Though they were attempting to rouse him, Justin remained unresponsive.

Scooter Braun, who discovered and now manages the "Boyfriend" singer, said he was unconscious for about five minutes after falling.

The footage from "Justin Bieber: All Around the World" was shown last week Wednesday, and the second part of the special is due to be viewed this Thursday.

Most fans are just happy Bieber is okay.

"Be careful Justin!!! I had a brother in law that used to do that same thing, its very easy to do if you are not watching what you are doing," wrote Ruby79 on the MSN.com blog.

"Thank God he has bodyguards," commented another fan.
